Permanent Magnet Variable Frequency Air Compressor

Permanent magnet variable frequency air compressor is a kind of air compressor using permanent magnet motor and variable frequency technology. Compared with traditional air compressors, permanent magnet variable frequency air compressors have the following significant advantages:

Energy saving: permanent magnet variable frequency air compressor can adjust the motor speed according to the actual gas consumption through variable frequency speed regulation technology, so as to achieve energy saving effect. Under normal circumstances, more than 30% of the electricity can be saved.

High efficiency: The permanent magnet motor has high efficiency, and the performance is more outstanding at low speed and high load. Combined with the speed regulation function of the inverter, the compressor can always operate at the optimal efficiency point.

Smooth start: frequency conversion start avoids the current shock and mechanical shock caused by traditional power frequency start, reducing the damage to the power grid and mechanical equipment.

Low noise: Due to the structure of the permanent magnet motor and the characteristics of frequency conversion speed regulation, the noise of the permanent magnet frequency conversion air compressor is lower during operation, providing a quieter working environment.

Simple maintenance: the permanent magnet motor has no brush and slip ring, reducing the maintenance workload and maintenance costs. At the same time, the inverter can provide a variety of protection functions, extending the service life of the equipment.

Intelligent control: The permanent magnet motor is equipped with an intelligent control system, which can monitor and adjust the operating parameters in real time to improve the automation degree and reliability of the system.

Permanent magnet variable frequency air compressors can be divided into the following categories according to different parameters and use scenarios:

Classification by power

• Low-power: usually the power is between 5.5kW and 22kW, suitable for small enterprises and light industry.
• Medium power: The power range is 30kW to 75kW, suitable for medium-sized enterprises and medium-sized industrial applications.
• High power: The power range is 90kW to 400kW, suitable for large enterprises and heavy industry fields, to meet the mass production and high demand of gas supply.

Classified by work pressure

• Low pressure permanent magnet variable frequency air compressor: the working pressure is generally between 0.7MPa and 0.8MPa, which is suitable for some occasions where the demand for low pressure gas supply is met.
• Medium pressure: the working pressure is between 1.0MPa and 1.25MPa, suitable for most industrial uses, covering a wide range of application fields.
• High-pressure: the working pressure is 1.5MPa and above, which is suitable for some special high-pressure occasions.
